State of (alifornia, havc invcn tcd an Im provon1cnt 111Camera-Adjnstcrs; and 1 hcreby (leclare thc .following t0 bc a 1'111],(elca1, aml cx- 1 c cf thc flangc fltting in thc socket cf thc actdescription 0f thc samc.

)Iy imc-ntion rclatcs t0 thc dass of ph0to graphic camcras, andcspccially t0 n1cans for acljusting and rcgulating the position 0f thccamera on the tripod; and my invention comsists in the combination of aplate secnrccl 011 the top of the tripod, a platc securccl t0 thc baseof the camera, and connections bctween saicl plates, whercby the lattermay havc an axial movement, a movement forwarcl ancl back, and amovement f101n siclc to siclc, as I shall hercinafter fully clescribe.

The object of my invention is t0 provicle a means for attaching thecamera to thc tripocl, of such character that the camera may turnaxially 10 any suitablc position, ancl may be acljnstcd to anyinclination up 01 Clown, ancl t0 any inclination laterally, so that,notwithstancling the position of the tripod, thc camera may 100 properlyadjnstccl.

Referring to the accompanying drawings for a more complete explanationof In invention, Figure 1 is a vcrtical section cf my ad juster, showingits application. Fig. 2 is a perspectivc view of the acljuster.

A is a plate aclaptecl to be securecl to thc t0p of the tripocl B.

C is a plate having a central screw, 0 whcrcby it may bc secnred to thebottom of the can1era D. Hingecl to thc plate A at e is a curveclbracket, E, l1aving a slot, e. This bracket may be movecl on itshinge-centers fron1 one sicle 1:0 thc other, pas'sing throughapproximately a siamicircle, and may be hold at any position in its1novementby means of a sct-screw, f, passing through aguiclc-arm, efitting over ancl slicling on a fixed curved guiderack, F, attached tothe plate A and against which the scrcw impingcs.

Fitted to the slotted curvccl bracket E is a tandard, G, adapted to bemovccl in the slot of thc bracket, ancl having a sctscrew, g, by whichit is fixecl in any position t0 which 111 may loe moved. This Standardhas a cylinlrical hcacl, g, provicled With an encircling groovc, q?, inits face, ancl With a socket, g in its centcr. The plate C, which isattachecl t0 thc camcra, has a (l0wnwarclly-cxtencling annnlar fiangc,(f, provirlecl with a ccntral pin, C, a1nlsaidflangc fits 0vcr thc heacl0f the standar l, wl1ich f0rms a jonrnal f01 lt, the pin standard. Asct-scrcw, II, passcs through thc flango c, and is adaptecl t0 fit inthc groovc g of thc stanclarclhcad and to bind the fiangc thcrcto,whereby the plate C is fixccl in placc.

lt Will bc sccn that thc plate C may havc an axizxl movc1ncnt abont thcstandarcl-hcad as a centcr, and 1nay bc fixecl by the scrcw H in anyposition t0 which lt may bc aclj ustecl. Bald plate may also havc a1novcn1ent forwarcl ancl back with the standard G in the slotted brackctE, whcrcby its vertical inclination may be detcrmincd and fixecl, anclsaicl plate 1nay also have a 1noven1cnt with the hinged bracket E,whereby its lateral inclination may be deterxninecl ancl fixed. Saidplate O bcing attachcd to the camera, thc latter itself has thesescveral movemcnts, and it follows that, 110 matter what 1nayloe thcposition of thc tripod, the camera niay bc properly adjusted by 0110 o11nore 0f the movemcnts which may bc impar tccl to it. T110 hingedbracket E also perm'1ts thc reversal 0f the camcra instantly, so as totake an imprcssion sixlewise of thc platc by letting thc lnackct downfrom a vertical position to a horizontal one, ancl this momment 0f theca-mera n1ay takc place 011 cither sicle, ancl thc camera may then byits axial movement bc suitably acljustccl.

Having thus clcscribccl my invention, what I claim as new, ancl (lesiret0 secnre by Letters Patent, is

l. In a camera-adjnstcr, a slotted curvccl bracket hingccl to thc tripodancl adapted to be turned fron1 a vertical to a horizontal position, incombination with a plate sccurecl to the camcra, said platc bcingadjustablc longituclin ally in thc slottccl curved bracket,substantially as herein describccl.

2. A camcra adjustcr for conneoting the camera With the tripocl,cornprising a hingecl slottcd curvecl bracket to loe securcd 110 thetripocl ancl aclaptcd to bc turncd from. a vertical to a horizontalposition, a standard fittecl t0 ancl afljustable longitudinally in theslotted IOO
